Header Help
I need some help deciding on some headers. They are for a 5.3 with mildly ported heads milled .040 with a tr224 cam. This motor is going in a 67 Camaro with a 5 speed manual and am going with the Dynatech swap headers with 1.875 primaries. My question is, should I get 2.5 or 3 collectors? Ive searched and cannot decide. Thanks for the help.

Sounds unanimous. I wasnt sure if 3 was going to hurt velocity on a 350-375whp motor. I was planning on running true 2.5 duals. Guess its better to step down gradually anyway. Thanks!
